What selenium does in the body
Selenium works inside selenoproteins, a family of enzymes that includes the glutathione peroxidases, which help to neutralise reactive oxygen, and the deiodinases, which activate thyroid hormone. Selenium contributes to normal spermatogenesis, to the maintenance of normal hair and to the maintenance of normal nails. Selenium also contributes to the normal function of the immune system, to normal thyroid function and to the protection of cells from oxidative stress.
Why L-selenomethionine
Selenomethionine is the form of selenium found in food, where it replaces methionine in proteins. It is absorbed more fully than inorganic selenite and is stored in the body’s proteins, which makes it a gentle, steady source. 100 mcg is 182% of the EU reference value of 55 mcg and a long way under the EFSA upper intake level of 300 mcg a day.
Who tends to run low
Selenium in food reflects the soil: much of Europe has low-selenium soils, so wheat, vegetables and meat grown there often contain less. Brazil nuts, fish, eggs and offal are the richest sources. People eating mostly plant foods from low-selenium regions are the likeliest to be short.
How to take selenium 100 mcg
One tablet a day with a meal. Do not combine several selenium sources, including other supplements, a multivitamin with selenium and a daily handful of Brazil nuts, because the margin between enough and too much is narrow and the upper level is 300 mcg a day.
Selenium and iodine are partners in the thyroid — see iodine 150 mcg. For antioxidant companions, vitamin E and vitamin C are the usual pairings, and the full list is in minerals.

Questions people ask
Can I take more than one tablet?
No. One tablet is the daily dose, and the upper intake level of 300 mcg a day applies to everything you take combined.
Does selenium go with iodine?
The two minerals work together in the thyroid, so they are often discussed together. If you have a thyroid condition, take advice before using either one.
How long can I take it for?
100 mcg a day is suitable for continuous use in healthy adults, provided that no other product adds selenium.
Good to know. Do not exceed the recommended daily dose. Food supplements should not replace a varied, balanced diet and a healthy lifestyle.
